Hi Mark, Some testing results to ponder
Just downloaded the new version 05.0538 and also tried the 05.0488 I think it was. Both of these versions are instantly causing Invalid page fault upon connection. If it doesn't connect due to comm issues etc, it will still live. As soon as "Command/Reply success" the fault kills SP.

The 05.0349 version connects fine when re-installed but is the slow version that everyone else was having problems with.
This is running Win98 SE with serial cable (not USB), 730 $8D Setup.
I have not been able to make a connection at all with the USB and APU1.

I didn't see anything and wondered if there was anything needed to be done with definitions to make them compatible with the newest versions?
Thanks,
John_________________
